Key defender Eric Mackenzie is signed up for next year and Vozzo indicated he would stay at the Eagles. The 2014 best and fairest struggled for a consistent spot in the senior team and only played 13 matches this season after missing all of 2015 following a knee reconstruction.

"We want him at the football club next year. It would have to be something exceptional for us to even consider moving him," Vozzo said.

"At this stage, he hasn't indicated that he wants to leave."

However, fellow backman Mitch Brown could be on the move.

"Mitch is an unrestricted free agent who is going to have a look at his options, given our strength with the tall backs," Vozzo said.

With the final salary cap figure yet to be decided for 2017, Vozzo said it had proved an impediment to making decisions on players.

"It's ridiculous. It's very difficult to run a business in a prudent way when you don't know what your budget is," he said.

"We've got a couple of guys who are waiting on those decisions, and as soon as we know that, we'll make our final list changes."

In coaching news, Peter Sumich won't return to the club after he declined a vacant line-coaching role. Former midfield coach Brady Rawlings was announced as the Eagles' new list manager earlier this week.

"It probably wasn't the role that (Sumich) was looking for," Vozzo said.

Sumich and Fremantle parted ways in August after he told the club he did not want to stay at the Dockers. He joined Fremantle in 2011, after having spent 11 years at the Eagles.
